Fertilizer is largely lost, and is polluted to soil and water body, the decline of crops resistance, serious to have threatened the sustainable of agricultural
Development.A variety of methods chemically and physically are had been presented for by exploration to solve the problems, such as that nitrogenous fertilizer dissolution is fast, utilization rate is low, are passed through
Long-acting sustained-release agent is added in fertilizer, the decomposition and inversion for inhibiting the activity of certain enzymes in soil to slow down nitrogen is the fertilizer benefit improved
With one effective way of rate.
A large amount of applications of inorganic fertilizer easily lead to soil fertility reduction, had both destroyed the acid-base balance of soil, and resulted in soil
The appearance of the problems such as decline of the earth content of organic matter, soil hardening.Biological humic powder is a kind of larger molecular organics matter, to changing
Soil, synergy and prevent and treat corps diseases, improve quality of agricultural product, soil and agricultural product prevented to be contaminated, enhance crops resist
Inverse ability all has facilitation, has preferably fertile utility value in general sustained slow-release fertilizer, but at present utilization and extention compared with
It is few.
The present invention joined a kind of biological humic in fertilizer in order to improve the fertilizer efficiency feature of general sustained slow-release fertilizer,
The humic acid molecular weight is small, active strong, and dissolubility is good, and the composite heat transfer is granulated using propylhomoserin and urinates what base whitewashing combined
Method, controlled release agent and biological humic are combined, improves soil fertilizer fertilizer condition while improving utilization rate of fertilizer, improves
Quality of agricultural product.
Summary of the invention
The present invention provides a kind of Humic acid synergistic type slow-release compound fertilizer particle, the life that the inner core particles of the compound fertilizer contain
Object humic acid is rich in organic matter, and dissolubility is strong, and molecular weight is small directly to be absorbed by crop, a variety of amino acid of microorganism generation,
The various actives substance such as plant hormone can promote root growth.Meanwhile the biological humic has certain slow-release function, it can chela
It closes the microelement in soil, reduce phosphorus fixation loss, effectively increase utilization rate of fertilizer, enhance the resistance of crop.Together
When, slow release layer is to add controlled release agent in urea slurry, can slow down urea hydrolysis rate in the soil and nitrification, is extended
Nutrient-lapsed time, the needs of meeting the crop middle and later periods to nutrient, prevent and treat early ageing.In addition, containing anti-caking in anti-caking oxidant layer
Agent, to prevent from agglomerating between particle.The scheme is as follows：
The embodiment of the invention provides a kind of Humic acid synergistic type slow-release compound fertilizer particle, each compound fertilizer granule from inside to outside by
Including inner core particles made of biological humic, the slow release layer made of sustained release agent and urea and the anti-caking made of anticaking agent
Block layer three-decker is combined.
Wherein, the inner core particles in the embodiment of the present invention further include nitrogen raw material, phosphorus element raw material, potassium besides urea
Raw material and middle microelement, wherein biological humic is that broken bagasse and animal wastes are formed by special microorganism bacteria fermentation.
Technical solution bring beneficial effect provided in an embodiment of the present invention is：
(1) biological humic that the inner core particles of the compound fertilizer contain is rich in organic matter, and dissolubility is strong, and molecular weight is small to be made
Object directly absorbs, and the various actives substance such as a variety of amino acid, plant hormone that microorganism generates can promote root growth.Meanwhile
The biological humic has certain slow-release function, can chelate the microelement in soil, reduce phosphorus fixation loss, effectively mention
High utilization rate of fertilizer, enhances the resistance of crop.
(2) slow release layer is to add controlled release agent in urea slurry, can slow down urea hydrolysis rate in the soil and nitrification
The needs of effect extends nutrient-lapsed time, meets the crop middle and later periods to nutrient prevents and treats early ageing.
(3) in addition, containing anticaking agent in anti-caking oxidant layer, to prevent from agglomerating between particle.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of Humic acid synergistic type slow-release compound fertilizer particle provided in an embodiment of the present invention.
In figure：1 inner core particles, 2 slow release layers, 3 anti-caking layers.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
Step ground detailed description.
Referring to Fig. 1, the embodiment of the invention provides a kind of Humic acid synergistic type slow-release compound fertilizer particle, the particle is rounded
Ellipse or class ellipse, wherein each compound fertilizer granule from inside to outside include biological humic made of inner core particles 1,
It is combined sustained release agent and slow release layer 2 made of urea and 3 three-decker of anti-caking layer made of anticaking agent.
Wherein, the inner core particles 1 in the embodiment of the present invention further include nitrogen raw material, phosphorus element raw material, potassium besides urea
